Title Direct infrared spectrophotometric analysis of free crystalline silica in respirable dust from a steel foundry
Bibliographic information Aug. 1981, Vol.42, No.8, p.579-585. Illus. 14 ref.
Abstract Respirable dust samples were collected on 25mm diameter Gelman VM-1 filters and were analysed directly with infrared radiation without any sample preparation. Field samples analysed using this method, redeposited infrared, and x-ray diffraction methods correlated well in the range 13-194µg. The direct infrared method is quick and simple and crystalline phase variants of free silica (quartz and cristobalite) appear to be distinguishable with infrared spectrophotometry.
